*************************

As a former Data Analyst for 3 years at Harmonie Mutuelle, I led the design of over 20 dashboards used by business teams. I then expanded my profile to Data Engineering with a certified training (~450h, MINES Paris/Liora), leading complete end-to-end projects: data warehouse, ETL pipelines, production deployment.

I am currently seeking freelance opportunities to leverage my expertise in data engineering, platform development, and advanced analytics.
